Dual PKM 48 Support - The Programmable Key Module 48 (PKM48) provides 48 additional feature keys for telephones.

Each feature key has a Line Status Indicator that behaves the same way as those on a phone.

A second PKM48 can connect to the first to provide for a total of 96 additional feature keys.

January 2012: Telefonix Voice & Date and Mitel have parted company, and we no longer carry the Mitel telephone system, deepening our specialisation in Avaya IP500 instead. This leaves us, however, in an excellent position to compare the Mitel 3300 phone system and the Avaya IP Office phone system: please contact us using the web or on 01252 333888 if you wish to discuss these phone systems.
